An electric valve, comprising a housing component and a valve body component, wherein the housing component is fixedly connected to the valve body component; a control component comprises a motor, and a control component is provided in an inner cavity of the housing component. With respect to the background art, the influence of moisture on the motor can be reduced.

A first flow channel of a flow channel switching valve includes a first portion that is connected to a valve body and that is linear, a second portion that is connected such that the second portion is perpendicular to the first portion and that is linear, and a lid member that is joined such that the lid member covers an opening of a tip end of the first portion. The first flow channel also includes a pair of projecting portions that is disposed such that the projecting portions interpose the first portion therebetween in a radial direction and face each other, and a connecting portion that couples the pair of projecting portions with each other. The pair of projecting portions includes a planar surface portion that faces the valve body direction.

The present disclosure describes a bi-valve for use with a flowmeter or other source of oxygen or other medical gas, that allows a medical practitioner to easily and quickly switch from delivering oxygen or other gas from the flowmeter or other gas source to a given mask or other device, to another mask or other device. This is accomplished far faster and easier than is done under current practice. Current practice results in the patient being off oxygen or other gas for a short, but very significant period of time, which poses a serious risk of desaturation in the patient. The bi-valve may include a casing, an inlet, and two outlets, with a knob for selecting which output the oxygen or other gas is to be delivered to. The device may be a very simple ball valve device, with the only moving parts being the knob and the ball.

An L-ball union drain valve member utilizes a union member with an L-ball valve that is coupled to a tee-shaped valve body with a drain port. The drain port includes an additional valve member that permits the draining/purging/filling of the drain port. The orientation of the drain port can permit the draining/purging/filling of different sections of the valve assembly, depending upon orientation of the components. The union connection permits easy disassembly and installation of the components and differing position of the handle of the valve member with respect to the tee-shaped valve body.

A dielectric union ball valve utilizes a non-conductive separation sleeve to prevent contact between the union and the nut of a dielectric valve assembly. The valve assembly can optionally include an independently operated drain valve port to permit draining of the valve assembly. The use and positioning of a non-conductive separation sleeve mitigates potential galvanic reaction between dissimilar pipes and/or fittings that are connected to the valve assembly.

A component for a ball valve that is configured to reduce noise. The component or “shoe” can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.

A 3-way T-flow ball drain valve permits the draining/filling/purging of a hydronic or plumbing system at the end of the line. This permits the orientation of a drain port in either horizontal or vertical position while permitting end of line draining. A drain valve member is positioned to permit the opening of the drain port when the T-ball valve member in the tee-shaped valve body has been open to permit flow toward the drain port.

An isolation valve unit with a fusion outlet including a valve body comprised of a metal, such as brass, and having at least two ports, at least one of the ports including an overmolded thermoplastic end surrounding and enclosing the port from which the fusion outlet extends. In one embodiment, the thermoplastic end is composed of a PP-RCT material and is securely formed over the port by way of an over molding technique. The valve unit further includes a ball valve accommodated within the valve body and a handle for actuating the ball valve. The isolation valve unit is configured to couple to a larger polymeric pipe and to control the flow of fluids in a plumbing system via actuation of the ball valve.

A test cock is configured to connect to a test cock port. The test cock includes a body portion defining a flowpath between a distal end and a proximal end. The test cock includes an intake stem at the proximal end that has external threads to connect the test cock to the test cock port. The intake stem defines an intake opening connected to the flowpath, the intake opening having a non-circular shape, such as a hexagonal shape. The test cock also includes an extraction tool having an end forming the non-circular shape of the intake opening, the end being sized to fit within and engage the intake opening.

A tank tee assembly includes a tank tee body including a tank tee inlet, a tank tee outlet and a tank tee passageway therebetween. An annular flange is disposed on a peripheral surface of the tank tee passageway. At least one through-hole structure is disposed in the tank tee body downstream of the annular flange. A poppet valve assembly is disposed in the tank tee passageway between the annular flange and the at least one through-hole structure. The poppet valve assembly includes a poppet and a guide. The guide is rigidly secured within the tank tee passageway. The guide includes a guide base. The guide base has an outside diameter that is larger than an inside diameter of the annular flange. The tank tee passageway is free of any threaded connections between the annular groove and the at least one through-hole structure.
